wnnnnn's HELMET.

Application filed April 2, 1925. -Serial No. 20,059.

he may swing the helmet above his head, and

thus causes inconvenience and loss of time to the welder when it is desired to inspect the work.

In helmets provided with strip springs for clamping the head band to the head, the hair is liable to catch between the springs and band and cause discomfort to the wearer.-

The objects of my invention are to provide 'a helmet which will sufficiently shield the eyes from the light rays of a welding arc; which may be swung to an open position in close and cramped places to give the eyes aclear view of the work; which will be yieldably held in open and closed position, and in which the head gear will be free of parts likely to be caught in the hair of the user.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a side elevation of a helmet made in accordance with my invention,

Figure 2 an enlarged central section through the helmet shown inFi ure 1,

Figure 3 a like view showing t e parts in another position,

Figure 4 an enlarged sectionon line 4-4; of Figure 2,

Figure 5 an enlarged section on line 5-5 of Figure 4C, and

Fi re 6 an enlarged section on line 66 of Figure 3.

Referrin to the drawings, 1 indicates the lower shiel ing section of a helmet adapted to shield the. lower part of the head of the user, 2 an upper shielding section adapted to shield the upper part of the head of the user having a hood 3 riveted thereto, and 4 a pair of bolts lvoting the sides of the upper section to t e sides of the lower section. Head gear 5 is pivoted on bolts 4. It includes a head strip 6, a reinforcing strip 7 and a top strip 8. These strips are secured to each other by rivets 9. The top strip has ts ends looped at 10 and secured to itself at 11. The loops are pivoted onbolts 4 on the inner side of the lower helmet section 1.

A coiled spring 12 is interposed between I the head of each pivot bolt 1 and a loop 10 for frictionally holding the loops of the head gear to the lower section. The tension of this spring may be varied by tightening a nut 13, on the threaded end of bolt 4, against the outer side of-the lower helmet section. For preventing a binding enga ement of the upper section 2' against t e lower section 1, a spacer 14, slightly thicker than the sheet material from which the upper section is made, is interposed between the outer side of section 1 and a washer 15. This arrangement allows varyin tension to be placed on spring 12 Without binding the upper section to the lower section.

The head strip 6 is of U-section and has strip springs 16 secured between the legs of.

the U. The curved partof the U forms the lower edge of the strip, so that when the head gear is fitted on the head, the curved edge will slide smoothly on the hair and will prevent s ring 16 from catching the hair.

To yiel ably keep upper section 2 in 0 en or closed position, a coiled spring 17 as one end connected directly to the upper section b a rivet at 18, and the other end connect indirectl to the lower section by a rin 19, pivote at 20 to a plate 21 secured to ower section 1. The connections 18 and 20 of rin 17 are so disposed that a line 22 passing t rough the connections, will be at one side of pivot bolt 4, when section 2 is in closed osition, as shown in Figure 2, and at the ot er side-of the bolt, when section 2 is in open position as shown in Figure 3. This arrangement of spring 17 tends to pull section 2 upwardly when in open position and downwardly when in closed position. The upward movement of section 2 is limited by an inclined edge 23 on the section 1 abut-' ting an edge 24 of hood 3. The downward movement of section 2 is limited by a ledge 25, integral with a shielding strip 26 secured to section 1, abutting an edge 27 of section 2. Strip 26v shields the eyes from the light rays that. may pass between .the meeting parts of sections 1 and 2. A metallic lens frame 28 is mounted on section 2 in such position that its edge 29 is flush 7 shown in Figure 3.

' section to open position a ove the head of section; an up its sides pivot with edge 27 and thus reinforces the same against wear caused by striking ledge 25. Suitable lenses 30 are mounted in the frame and held by a spring strip 31 between a pair of ribbed lugs 32 on lens frame 28. A cross piece 33 of V-cross-section is pivotally secured to the sides of helmet section 1' at 34:. This cross piece reinforces section 2 and abuts the chin of the user to hold the-helmet in proper position relatively to the head, as

To apply the helmet, the head gear is slipped over the head so that head strip 6 slides on the hair until top strip 8 abuts the top of the head as shown in dot-and-dash lines'in Figure 3. Cross piece 33 is then adjusted on its pivots 34 to the proper pos1 "tion against the chin. To inspect the work with the naked eye,.it is merely necessary to swing the upper section 2 from the position shown in Figure 1 to the position shown in Figure 2. This ives the eyes a wide view of the work, in front and at the sides of the helmet. The upper section is.

held in this open position by the action of coiled spring 17 tending to raise section 2 against the inclined edge 23 of lower section 1. After inspection of the work, section 2 'is lowered until its edge- 27 abuts ledge 25. Section 2 is held in this position by the action of coiled spring17 tendin downwardl against ledge 25. oiled spring 17 thus yie dingly holds section 2 in open or closed position. Shielding strip 26 prevents light rays from passing between ledge 25 and edge 27 and serves to support ledge 25.

By making a helmet in sections and connectmg the sections as above set forth, a section of the helmet may be easily swung upward to give the eyes a wide view of the work when the welder is in close and cram d places.

Wl ii le I-have described my invention as taking a particular form, it will be. understood that the various parts may be changed without departing from the s irit thereof, and hence I do not limit myse f'to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
